UUU Custom IMX8MM Board

Hello all,

This is another update for this issue,

After passing the calibration and stress test and generating ddr3_timing.c file,

I tried to rebuild the u-boot-imx with the new file, and its correctly built,

but when flashing the board with UUU I got a failure, and the log output of minicom is attached.

I found many other people facing this problem with imx6 and 7, and the answers are generally to modify the imx8mm_val.h file under u-boot-imx to set the settings of DDR there too.

Any help?

Thanks again.
